// GPT Researcher is an autonomous deep research agent that conducts web and local research, producing detailed reports with citations. Use this skill when helping developers understand, extend, debug, or integrate with GPT Researcher - including adding features, understanding the architecture, working
GPT Researcher Development Skill
GPT Researcher is an LLM-based autonomous agent using a planner-executor-publisher pattern with parallelized agent work for speed and reliability.
Quick Start
Basic Python Usage
from gpt_researcher import GPTResearcher
import asyncio
async def main():
researcher = GPTResearcher(
query="What are the latest AI developments?",
report_type="research_report", # or detailed_report, deep, outline_report
report_source="web", # or local, hybrid
)
await researcher.conduct_research()
report = await researcher.write_report()
print(report)
asyncio.run(main())
Run Servers
# Backend
python -m uvicorn backend.server.server:app --reload --port 8000
# Frontend
cd frontend/nextjs && npm install && npm run dev

Core Patterns
Adding a New Feature (8-Step Pattern)
- Config → Add to
gpt_researcher/config/variables/default.py - Provider → Create in
gpt_researcher/llm_provider/my_feature/ - Skill → Create in
gpt_researcher/skills/my_feature.py - Agent → Integrate in
gpt_researcher/agent.py - Prompts → Update
gpt_researcher/prompts.py - WebSocket → Events via
stream_output() - Frontend → Handle events in
useWebSocket.ts - Docs → Create
docs/docs/gpt-researcher/gptr/my_feature.md
For complete feature addition guide with Image Generation case study: See references/adding-features.md
Adding a New Retriever
# 1. Create: gpt_researcher/retrievers/my_retriever/my_retriever.py
class MyRetriever:
def __init__(self, query: str, headers: dict = None):
self.query = query
async def search(self, max_results: int = 10) -> list[dict]:
# Return: [{"title": str, "href": str, "body": str}]
pass
# 2. Register in gpt_researcher/actions/retriever.py
case "my_retriever":
from gpt_researcher.retrievers.my_retriever import MyRetriever
return MyRetriever
# 3. Export in gpt_researcher/retrievers/__init__.py
For complete retriever documentation: See references/retrievers.md
Configuration
Config keys are lowercased when accessed:
# In default.py: "SMART_LLM": "gpt-4o"
# Access as: self.cfg.smart_llm # lowercase!
Priority: Environment Variables → JSON Config File → Default Values
For complete configuration reference: See references/config-reference.md
Common Integration Points
WebSocket Streaming
class WebSocketHandler:
async def send_json(self, data):
print(f"[{data['type']}] {data.get('output', '')}")
researcher = GPTResearcher(query="...", websocket=WebSocketHandler())
MCP Data Sources
researcher = GPTResearcher(
query="Open source AI projects",
mcp_configs=[{
"name": "github",
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {"GITHUB_TOKEN": os.getenv("GITHUB_TOKEN")}
}],
mcp_strategy="deep", # or "fast", "disabled"
)
For MCP integration details: See references/mcp.md
Deep Research Mode
researcher = GPTResearcher(
query="Comprehensive analysis of quantum computing",
report_type="deep", # Triggers recursive tree-like exploration
)
For deep research configuration: See references/deep-research.md
Error Handling
Always use graceful degradation in skills:
async def execute(self, ...):
if not self.is_enabled():
return [] # Don't crash
try:
result = await self.provider.execute(...)
return result
except Exception as e:
await stream_output("logs", "error", f"⚠️ {e}", self.websocket)
return [] # Graceful degradation
Critical Gotchas
| ❌ Mistake | ✅ Correct |
|---|---|
config.MY_VAR | config.my_var (lowercased) |
| Editing pip-installed package | pip install -e . |
| Forgetting async/await | All research methods are async |
websocket.send_json() on None | Check if websocket: first |
| Not registering retriever | Add to retriever.py match statement |
